Andersen vs Renewal by Andersen: Dealer-Sold Windows vs the In-House Replacement Division
Both brands share Andersen's Fibrex composite material, but they are sold through entirely different channels with separate warranty documents. The practical choice is about installation model, not frame material.
Updated August 2026
Who wins what
Homeowners who want to solicit competing bids from multiple installers carrying the same brand.
Basis: Andersen's 100 and 400 Series are sold through a network of independent dealers, allowing homeowners to compare quotes from different installers on the same product line.
Homeowners who prefer one company handling the sale, measurement, and installation without a separate third-party contractor.
Basis: Renewal by Andersen operates its own direct sales and installation division, so the same company that sells the window is contractually responsible for installing it, unlike Andersen's dealer-distributed lines.
Everyone, since neither brand publishes installed pricing.
Basis: Neither Andersen nor Renewal by Andersen publishes installed pricing; quotes are set by the dealer or installation division, so no defensible winner exists without a local bid.

Which one is right for you?
Choose Andersen if…
- You specifically want Fibrex composite (100 Series) and wood with aluminum cladding (400 Series, E-Series) and a quote from independent dealers and select big-box retail (100 Series at The Home Depot) instead of Renewal by Andersen's Fibrex composite, the same base material family used in Andersen's 100 Series.
- Independent dealer choice is the deciding factor over Renewal by Andersen for this need.
- A local Andersen dealer or division has stronger reviews and faster lead times than the Renewal by Andersen option available to you.
Choose Renewal by Andersen if…
- You specifically want Fibrex composite, the same base material family used in Andersen's 100 Series and a quote from Renewal by Andersen's own direct sales and installation division; it is not sold through independent third-party dealers instead of Andersen's Fibrex composite (100 Series) and wood with aluminum cladding (400 Series, E-Series).
- Single-source installation accountability is the deciding factor over Andersen for this need.
- A local Renewal by Andersen dealer or division has stronger reviews and faster lead times than the Andersen option available to you.
Choose neither if…
- Your current windows still seal and lock properly and the issue is condensation, drafts, or worn hardware rather than frame failure, in which case a repair avoids the cost of a full Andersen or Renewal by Andersen replacement.
- You have not yet requested a written, itemized quote from a local Andersen dealer and a local Renewal by Andersen dealer, so this comparison has nothing concrete to weigh yet.
- Neither Andersen nor Renewal by Andersen has an active dealer or installation crew reasonably close to your address, making a third brand the practical choice regardless of how they compare on paper.
The short answer
Andersen and Renewal by Andersen differ mainly in frame material, sales channel, and how each documents its warranty. Neither publishes installed pricing or an independently verified reliability ranking, so the comparison here is limited to what each manufacturer states in its own product and warranty documentation.
Cost breakdown
| Line item | Andersen | Renewal by Andersen |
|---|---|---|
| Window unit, mid-size double-hung or casement | Not published by the manufacturer | Not published by the manufacturer |
| Installation labor | Set by the independent dealers and select big-box retail (100 Series at The Home Depot) | Set by the Renewal by Andersen's own direct sales and installation division; it is not sold through independent third-party dealers |
| Removal and disposal of old windows | Set by the installer | Set by the installer |
| Custom sizing or specialty shapes | Priced per quote where offered | Priced per quote where offered |
Neither Andersen nor Renewal by Andersen publishes installed window pricing, so this table lists cost categories instead of invented dollar figures. Ask each dealer or installer to itemize the unit price, labor, and disposal separately so quotes are comparable across brands.
Long-term value
For Andersen and Renewal by Andersen alike, long-term performance hinges on correct flashing and installation more than on which name is on the frame. Ask the installer what workmanship coverage they provide and whether either manufacturer's warranty is voided by non-professional installation, since both companies' documents include installation conditions.
Decision framework
Andersen documents this material as part of its published lineup; Renewal by Andersen does not offer the same configuration.
Renewal by Andersen documents this material as part of its published lineup; Andersen does not offer the same configuration.
Installation quality and warranty validity depend on the installer, which matters more locally than the brand comparison itself.
Entry-level and premium lines from the same brand can differ as much as two different brands, so align tier before comparing across brands.
- Comparing a bid for Andersen's most affordable line against a bid for Renewal by Andersen's flagship line and concluding the price gap reflects a brand-wide difference rather than a tier difference.
- Assuming the warranty length quoted for Andersen or Renewal by Andersen covers installation labor, when both companies' warranty documents separate material and glass coverage from labor, which the installer prices independently.
- Relying on Andersen's or Renewal by Andersen's marketing pages for U-factor instead of looking up the NFRC-certified rating for the exact model and glass package written on the quote.
- Not confirming with the Andersen or Renewal by Andersen dealer whether the written warranty requires professional installation to stay valid, since both brands' warranty documents list installation conditions.
- Treating the Andersen or Renewal by Andersen name itself as proof of good installation instead of checking reviews and references for the specific local dealer or crew doing the work.
